Have you solved this problem? Try with ' *root* ' for password. Hector Bojorquez

Both of those ip addresses are on separate subnets. They will not be able to talk to each other. Do you have an IT person who would be able to help you get the networking setup correctly?
It would be helpful if you explained how you ... Jonathan Cormier

Hi Nourhan,
Did you check that your COM port is the correct one?,

You should be able to force it to check for an ip address by running @udhcpc -i eth0@. Or something similar I don't have one at home to test with. Jonathan Cormier

NE 05:04 PM Software Development: RE: Mity DSP L138F program

isnt the dsp at eth0?
in this case i dont even have an IP address. Nourhan Elsayed

JC 04:55 PM Software Development: RE: Mity DSP L138F program

Have you connected your devkit straight to your PC? That ip address is usually assigned by windows if no dhcp server is found. http://www.techrepublic.com/forums/discussions/where-did-ip-16925451183-come-from/

The 192.168.1.125 address you are using is the address of the VM. You need to use the address for the L138. Jonathan Cormier

There is no root password set. If you login as user root and press enter when asked for password it should let you in. Jonathan Cormier
